Solutions for solar energy

Solar plants will be more and more a constant element of our infrastructure and environment.

Not only the thousands of photo-voltaic elements already visible on the roof of many houses

worldwide, but also the impressive solar fields of hundreds of heliostats placed in wide and

uninhabited areas too, producing hundreds of megawatts by converting the sun‘s energy into high-

temperature heat using different mirror configurations.

Encoders and other measuring systems used for the control of the mirrors must withstand a variety of

harsh environmental challenges. The key-factor is the continuous and efficient operation of the plants.

Downtimes, poor operating performance and replacements cause not only waste of time but are a

sensitive cost-efficiency factor.

The Kübler Group manufactures its products with the goal to withstand the toughest environmental

challenges. Rugged construction and innovative technologies combine to give reliable performance to

the installation and assure efficiency in the energy generation process.

Kübler products for solar energy. Rugged and reliable.

The Sendix rotary encoders have been specially designed for outdoor applications with their compact die-cast housing technology, wide temperature range (from -40°C to 85°C) and high IP protection rate of up to IP67.They can be used in stand-alone systems or can be integrated into drives.Heliostats in particular demand high precision and therefore the optical Sendix encoders are the best option for this type of application.The Sendix family offers all types of interfaces - incremental, SSI, BISS or all commonFieldbus protocols - depending on the automation network.

Elevation and azimuth position control of heliostats

A power tower converts sunlight into electricity to be distributedthrough the grids.This technology uses many large, sun-tracking heliostats to con-centrate sunlight on a receiver positioned on the top of a tower. A heat transfer fluid or molten salt heated in the receiver is used to generate steam, which is directed into a turbine generator to produce electricity.

An important contribution to the efficiency of the system dependson the positioning accuracy of the heliostats in elevation andazimuth. The heliostats are typically positioned in desert areas andthe equipment is exposed to environmental factors such as large temperature differences between day and night, high temperatures during the day and constant dust presence. The maintenance operation and possible downtimes must be reduced to the lowest level possible.

Elevation and azimuth control in photovoltaic installations have low accuracy requirements. Therefore inclinometers are an ideal economical alternative.The IN series has an extraordinarily compact and robust aluminium housing, together with a high protection class IP67/IP69k. The temperature range goes from -40°C to +85°C. Those sensors use analogue or CANopen outputs for 1 or 2 dimensional inclinations. Depending on the version, different measurement ranges are possible. Programmable vibration suppression, calibration accuracy (at 25°C) ±0.4° and zero point adjustment are further highlights of the IN inclinometers.

The measurement of the angular position of Parabolic Trough Systems can be carried out using robust and simple magnetic encoders or with inclinometers, depending on the installation space available.For installation directly on the shaft, the standard Sendix magnetic rotary encoders can be used. The Limes system with customised magnetic bands is the solution for applications with very restricted installation space.Inclinometers offer the easiest installation directly on the panel.

Angular position control of Parabolic Trough Systems

The parabolic trough belongs to a field including hundreds of them in parallel rows aligned on a north-south axis. Each one follows the sun on a single-axis from east to west, keeping the sun rays continuously focused on the receiver pipes. Here it is best to use a simple, rugged and flexible measuring system.

A parabolic mirror concentrates the sun‘s energy, thanks to its curved surface, onto a receiver pipe running along the inside of the curved surface. This energy heats oil flowing through the pipe, and the heat energy is then used to generate electricity in a steam generator.

Technologies for solar energy

Innovations come from experience. Kübler products benefit from 55 years experience in automation engineering. Over the years they have undergone ongoing development and been optimised for use in drives, in outdoor and offshore applications and not least in solar energy.Small details make a big difference. Our products feature many intelligent, high-quality extras, whichoffer our customers technical advantages which give a significant contribution to the availability of theplant and reduction of downtimes.

Rugged bearings: Safety-Lock™ . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

The Sendix encoders offer higher reliability and longer service life,offer a very sturdy, rugged bearing construction as a result of theKübler Safety-Lock™ technology. Encoders with Safety-Lock™ tolerate installation errors and high loads on the shaft, such as occur with wide temperature fluctuation or vibration.Interlocked, positive-fitting bearings, large bearing spans and aspecial assembly technique make a contribution here.

Optical encoder technology. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

100 percent resistant to magnetic fields – extremely compact design. Even strong magnetic fields, as occur in the vicinity of brakes or drive motors, pose no problems for the sensor technology of optical encoders.The technology dispenses with any components that may be susceptible to magnetic influences and allows for high scanning rates. The multiturn gear module – developed from specialmaterials – is effective thanks to its double bearing layer and thespecially developed gear teeth, resistant against wear, and can be used for high speeds up to 9000 rpm. As a result of the proven drive, the encoder has no need of a battery to store the number of revolutions.

Magnetic sensor technology. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Magnetic sensors are particularly robust while having a compactstructure. The magnetic technology allows fully encapsulatedelectronics and thus an IP69k protection. They offer aparticularly economic solution for short strokes, applicationsrequiring a high repeatability accuracy or for manual positionmonitoring.

Seawater resistant. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Although it has already proved itself in harsh environments, the Sendix encoders family has been tested and certified according to the IEC 68-2-11 standards about resistance to the effects of salt-spray water over a period of up to 672 hours – the highest test level. The high certification level for the Sendix encoders gives further reliability for a high level of resistance against corrosion.

Shock and vibration resistant. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Kübler encoders avoid serious, expensive failures right from the start – even with increased levels of axial loading, shock and vibration. This can eliminate enormous service costs and expensive downtimes in plants and installations worldwide. The high IP protection level makes these devices lesssensitive to wet conditions outdoors, and for temperatures between -40°C and +90°C or for altitudes over 3000 meters above sea-level.

Housing technology for outdoor use. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

The strong die cast housing of the Sendix encoders has extra thickwalls. It is fastened to the encoder flange by multiple crimping. Thehigh protection (up to IP69k) and the wide temperature range from-40°C to +90°C allow an outdoor use without any problem. The diecast housing has a very strong base, on which the connector flange is fastened with four screws.The Sensor-Protect™ design of the M36 encoders allows, thanks toentirely compound-filled electronics, the highest protection, IP69k.Thanks to the separate mechanical components with mechanicallyprotected shaft and labyrinth seals, no additional protection isrequired in case of steam or highpressure cleaning.
